When deciding to acquire property, real estate asset managers take several factors into consideration, such as property values, taxes, zoning, population growth, transportation, and traffic volume and patterns. Once a site is selected, they negotiate contracts for the purchase or lease of the property, securing the most beneficial terms. Real estate asset managers periodically review their company's real estate holdings and identify properties that are no longer financially profitable. They then negotiate the sale of or terminate the lease on such properties. Real estate asset managers must be good negotiators, adept at persuading and handling people, and good at analyzing data in order to assess the fair market value of property or its development potential.
